MACHINE FOR ROLLING EYE-BARS.

SPECIFICATION forming part of Letters Patent No. 349319, dated September21, 1886.

Application filed April 7, 1886. Serial No. 198,089. (No model.)

States, have invented or discovered certain new and usefulImprovementsin Machines for Rolling Eye-Bars, of which improvements thefollowing is a specification.

In the accompanying drawings, which make part of this specification,Figurel is a viewin front elevation of my improved mill for rollingeye-bars. Fig. 2 is a plan view of the rotating bed. Fig. 3 is a view infront elevation, on an enlarged scale, of a portion of the mill, certainparts being shown in section. Fig. 4 is a vertical sectional view on theline a: at, Fig.3. Fig. 5 is a horizontal section on the line y y, Fig.3. Fig. 6 is a detail view of a modification of the edging device.

The invention herein relates to certain improvements in mills forrolling eye-bars, and

I has for its object such a construction and arrangement of parts aswill effect a reduction and elongation of the body portion of a billet,and also the reduction and spreading of the end portions thereof for thepurpose of form ing a suitably-shaped head 5 and it is a further objectof said invention to so shape the ends of the billets that thelongitudinal back and forth passes of the billet between the rolls willproduce the desired enlargements on the ends of the bars.

In general terms the invention consists in the constructionandcombination of parts, substantially as hereinafter described andclaimed.

In suitable housings, 1, are mounted the rolls 2, having operative facessomewhat wider than the heads of the bars to be rolled. These rolls aredriven by the usual or. any suitable form of driving mechanism, as shownat A, in Fig. 1, and the upper roll is provided with the usualscrew-adjusting mechanism, B. On the ends of the rolls, projectingbeyond thehousings, are formed the collars 3, having curved operativefaces, as shown in Fig. 1. Between the housings 1 on each side of therolls are secured the horizontal bars 4, on which are supported theinner ends of the feed-tables 5, having their upper surfaces tangentialto the periphery of the lower roll, as shown in Fig. 4,

On the inner sides of the housings and on each-side of the rolls arebolted the brackets 8 and 9, between which are mounted the boxlikeframes 10, provided on their outer sides with a rack, 11, arranged tointermesh with the pinions 12, keyed to the shaft 13, mounted insuitable bearings bolted to the sides of the housings, andprovided withan operating hand-wheel, 14, whereby the frames 10 may be reciprocatedsimultaneously. The ends of the frames 10 are connected and braced bythe bars 15, said bars passing under the tables 5, as shown in Fig. 4.About midway of the frame 10 is formed therein a box, 16, for thereception of a journal-box, 1 7, in which is mounted the axle of thevertical roll or disk 18, said roll being arranged to operate inahorizontal plane passing between the rolls 2, as shown in Fig. 3. Thesej ournal-boxes are adjustable toward or away from each other by means ofliners 19. At one side of the housings, and in planes parallel with theaxes of the rolls-2, are arranged suitable guideways, 20, on which isplaced a movable bed, 21, constructed to move back and forth on theways, and having attached thereto a threaded rod, 22, said rod passingthrough a rotating nut, 23, mounted in a suitable journal formed on thepost 24 at the end of the'ways 20, and provided with an' operatinghand-wheel, 25, whereby the nut 23 may be rotated and the bed 21 movedback and forth along the ways. On this bed 21 is placed a horizontalplatform, 26, having a central pivot-pin fitting within a suitableopening in the loed. The platform is provided with two movable jaws, 27,actuated toward and from each other by the right and left hand threadedrod 28. (See Fig. 2.)

In rolling eye-bars a billet of approximatelythe width desired in thefinished bar is heated to the desired rolling heat, the bed 21 havingbeen adjusted at such a distance from the hous-. ings that the end ofthe billet will, in the rotation of the platform 26, pass betweencollars 3 of the rolls 2. The bar is then clamped upon the platform. Theplatform is then rotated in order to feed one end of the billet betweenthe collars 3. Theimpetusiimparted to the billet and platform by theaction of the collars will generally be sufficient to bring the oppositeend of the billet around into engagement with the collars. Thisoperationis continued, the rolls being adjusted toward each other afterthe rolling of each end until the portion of the billet acted on by thecollars is reduced to or approximately to one-half the thickness of thecompleted bar. By the action of the collars a transverse groove isformed in the billet at each of its ends, as shown at ain Fig. 1, and atthe same time lateral wings or enlargements I) are formed in line orapproximately so with the groove (0. (See Fig. 2.) The billet is thenremoved from the platform 26, and the frames 10, with the vertical rolls18, having been removed to the position shown in Fig. 5, the billet isplaced on one of the tables 5, with the wings I) at one end of thebillet on one side of the vertical rolls, and the wings at the oppositeend on the other side of said rolls, the body of the billet lyingbetween them. The frames 10 are now moved forward by means of thehand-wheel 14 and intermediate connections, and as the vertical rolls 18encounter the wings I) of the billet they move the latter forward untilit is caught by the rolls 2. The vertical rolls are moved along by thehand-wheel until their axes are in or approximately in the same verticalplane as the axes of the horizontal rolls, and are held in that positionby the operator through the medium of the hand-wheel 14 until the wingsb on the opposite end of the billet strike against said rolls, and carrysaid rolls and the frames 10 to the opposite side of the rolls 2, theoperator releasing the hand-wheel simultaneously with the engagement ofthe wings I) with the rolls 18. As soon as the billet has passed betweenthe rolls 2 in one direction, as above described, the operator reversesthe hand-wheel, thereby reversing the movement of the frame 1.0 androlls 18, and again feeds the billet to the rolls 2, which have alsobeen reversed. The rolls 18 are again stopped when between the rolls 2,as above stated, until' moved away therefrom by engagement with thewings I) on the end of the billet. This operation is continued until thedesired reduction and elongation of the billet is effected. The rolls 18serve to prevent any lateral enlargement of the billet during therolling operation, and also to feed the billet to-the horizontal rolls,as above described, and to square the edges on the finished bar. During'this longitudinal rolling operation, above described, the body of thebar is elongated and reduced in thickness, and the wings I) arebroadened or spread out in lines parallel with the length of the bar.

The notehing or grooving operation first described effects such adistribution of the metal at the ends of the bar that the subsequentrolling operation will produce an approximately cireular head on thebar, as shown in Fig. 5.

In operating the above-described mill, the two rolling operations arecarried on simultaneously or separately, as desired.

The roll 18 is made of a width not greater than the thickness of thecompleted bar, and in lieu of rotary edging disk or roll 18, astationary disk (see Fig. 6) may be employed to perform the gripping oredging functions, as will be clearly understood.

The bed 2]., after being once adjusted for a certain length of billet,is kept stationary until billets of a different length are to be rolled,and the table or platform may be made movable transversely of the axesof the rolls,2.

I claim herein as my invention 1. In a mill for rolling eye-bars, thecombination of a pair of horizontal rolls and a pair of vertical rolls,having, in addlti'on to a rotary motion, a motion in the generaldirection of the feed to or toward, as well as away from, the point ofbite of the horizontal rolls, sub stantially as set forth.

2. In a mill for rolling eyebars, the combination of a pair ofhorizontal rolls, and a single mechanism for feeding the article to berolled to the horizontal rolls, the same mechanism being alternativelyoperative on both sides of the horizontal rolls, substantially as setforth.

3. In a mill for rolling eye-bars, the combination of a pair ofhorizontal rolls having operative faces between the housings, the endsof said rolls projecting beyond one of the housings,said proj cctingends provided with grooving-collars and a movable table or support forfeeding the ends of the article to be rolled to said grooving-collars,thereby so shaping the I ends of a billet that the subsequent action ofthe rolls will produce the desired enlargements on the ends of the bars,substantially as set forth.

4'. In a mill for rolling eye-bars, the combination of a pair ofhorizontal rolls having operative faces between the housings, the endsof said rolls projecting beyond one of the housings and provided withgrooving-collars, and a rotating table for feeding the ends of thebillet to said grooving-collars, whereby the ends of the billets aresuitably shaped with reference to the formation of enlargements on thebars by the action of the rolls, substantially as set forth.

5. In a mill for rolling eye-bars, the combination of a pair ofhorizontal rolls, guides lobox, 16, and an edging-disk mounted in said10 box, substantially as set forth.

In testimony whereof I have hereunto set my hand.

HENRY AIKEN.
